Maple tech support sent me a third party application for my Maple 2016 to solve a problem that I'm working on. I was instructed to copy and paste a few items from the download: "to your "<maple>/lib" folder" Unfortunately I cannot access "lib" in my Maple "Applications" folder on my OS X MacBook Pro.

This is what Maple Tech Support sent me:

"Another option you may want to look into is the "DirectSearch" package (which is third-party, and not supported by us), which would need to be downloaded from the Maplesoft Application Centre:




There is a function "GlobalOptima()", which allows one to search for a global minimum to the objective function, as opposed to a local minimum like commands such as "LSSolve()". To install, you can extract the files "DirectSearch.mla", "", and "DirectSearch.hdb" to your "<maple>/lib" folder."


Any suggestions?

We find recent applications of the components applied to the linear momentum, circular equations applied to engineering. Just simply replace the vector or scalar fields to thereby reasoning and use the right button.

Currently calculations: equations, regression analysis, differential equations, etc; to mention a few of them; are developed using traditional methods ie even are proposed and solved by hand and on paper. In teaching our scientists and engineers use the chalkboard as a way to reach students and enable them to solve their calculation. To what extent Maple contributes to research on new mathematical models applied science and engineering ?. Maplesoft appears as a proposal to resolve problems with our traditional proposed intelligent algorithms, development process, embedded components, and not only them but also generates type applications for Apple ipad tablets signature. Based on the computer algebra system Maple Maplesoft gives us the package which works exactly like we were on our work. I will show how mathematics is developed from a purely basic to reach modeling differential equations applied to education and engineering. Also visualizare current techniques for developing applications for mobile devices.

Today science professionals in engineering software used to only work on the desktop and even just looking to download and use mobile apps math; but they are not able to design their own applications.Maplesoft to set the solution to it through its Maple package; software supports desktop and mobile; solves problems of analysis and calculation with Embedded Components. To show this we have taken the area of different mathematical topics; fixed horizontally to a certain range of parameters and not just a constant as it is customary to develop. This paper shows how the Embedded Components allow us to develop mathematics in all areas. Achieving build applications that are interactive in mobile devices such as tablets; which are used at any time. Maple gives us design according to our university or research need, based on contemporary and modern mathematics.With this method we encourage students, teachers and researchers to use graphics algorithms.

I would like to pay attention to a series of applications by Samir Khan
My congratulations to the author on his work well done. New capacities of Global Optimization Toolbox are spectacular. For example, in the first application  an optimization
problem in 101 variables under 5050 nonlinear  constraints
(other than 202 bounds) is solved.
I think it requires a very powerful comp and much time.
I tried that  problem for n=20 with the good old DirectSearch
on my comp (4 GB RAM, Pentium Dual-Core CPU E5700@3GHz) by

soln2 := DirectSearch:-GlobalSearch(rc, {cons1, cons2, rc >= 0,
seq(`and`(vars[i] >= -70, vars[i] <= 70), i = 1 .. 2*n), rc <= 70},
variables = vars, method = quadratic, number = 140, solutions = 1,
evaluationlimit = 20000)

and obtained not so bad rc=69.9609360106765 (whereas gives rc=58.4005674790451137175957) in about one hour.
For n=50 the memory of my comp cannot allocate calculations or the obtained result by the Search command is far away from the one in packomania.


In Maple 18, the Database package has been updated to include support for SQlite databases as well as a new option for plots to change the background images on plots.  To showcase both of these features, our engineering team put together an example that optimizes the flight path of a pan-US delivery drone.

This application extracts the latitude and longitude of those zip codes from an SQLlite database (the application includes the database, which cross-references US zip codes against their latitude, longitude, city and state). The application then performs a traveling salesman optimization and plots the shortest path on a map of the US.

I installed the shared library from

and it seems to have loaded ok. Now I can do

See ?share and ?share,contents for information about the share library

When browsing help, I noticed it has a function called IntSolve() for solving linear integral equations. Maple itself has function called intsolve() which is build-in.

Since Maple is case sensitive, I assumed when I type IntSolve() then it will find the shared version of IntSolve() automatically and not call Maple's own intsolve. And that is indeed what happed. I typed an example from the help on share as you can see


eq1 := p(x)-1/2*Int(x*y*p(y),y=0....1)=5/6*x;
                             ---- x
                            p(x) = x

Ok, So one of them is a little wrong :).

But suppose I want to explicitly add the share library there, in the call, as prefix, so that when I look at the code later, I can see which function I am calling. How should one do this? I tried

    Error, `share` does not evaluate to a module


The strange thing, is that this worked


Basically, all what I want is to way to add the share name to all the calls somewhere, so I know, when looking at the code, which call is from which library or package.

Any idea how to do this? So to avoid any possible name clash since the share library seems large.

I am using Maple 17.02

Maple IDE is the only Eclipse™ based efficient development toolkit to rapidly build standout applications for one of the most powerful Computer Algebra Systems.

I'm looking for several challenging projects for a Calculus II course using Maple which I'll be teaching in Spring 2013.  By challenging I mean that the project will have several steps including both conceptual and computational aspects.  I'd also like them to be suitable for group work if possible.  I'd be willing to devote from 3-5 class periods for each of three or four different projects.  Our Calc I and Calc II are five hour...

We are proud to announce you about the new feature in the Maple Programming Environment - Importing existing MPL files into a Maple Project.

You can update Maple Programming Environment using Update Manager mechanism in the Eclipse.

The following article briefly introduces the migrating process using the new import wizard,...

Maple Programming Environment (MPE) is the only Eclipse™ based efficient development toolkit to rapidly build standout applications for Maple.

MPE harnesses the flexibility of Eclipse and focuses it into a powerful Maple development engine.

MPE includes multiple productivity-boosting features, which spare you from tedious routine, time loosing and keeping your focus on your ideas.

Any word on an applications collection DVD(s) from maplesofts applications center for offline browsing?
I had made the suggestion a while ago.  What is the status of that project?  Is it still under consideration?

I thought it could be purchased seperately, or included in new releases of Maple.

  * All the applications in the application center in a similar browsable format
  * Update button that updates a folder on your...

Just a curious question.

Why when some new applications are added to the application center they do not always get inserted at the top of the list? 


One of the challenges in Linear Algebra is in developing problems, projects, and exercises that are both larger dimensional and student-accessible. Indeed, round-off error, computational complexity, difficulty factoring characteristic polynomials of degree 3 or higher, and similar aspects often mean that any problems or applications of rank 3 or higher are approached solely via technology. 

However, that same technology can be used to create...
